DC twin rotary compressors are most congenial with R410A
and are used within the outdoor units. All compressors are
driven by a High-speed Calculation Vector Control Inverter.

Foreword
1. OUTLINE OF TOSHIBA SUPER HRM
(Super Heat Recovery Multi System)
Shortest route design by free branching
The Combination of line and header branching is highly flexible.
This follows for the shortest design route possible, thereby saving
on installation time and cost. Line/header branching after the
header branching is only available with TOSHIBA Super HRM.

Energy saving
No.1 COP in heat recovery VRF industry.Compared with the conventional chiller fan coil system,
a large energy saving can be achieved.
Advanced bus communication system
Wiring between indoor and outdoor units is a simple 2 core wire system.
Communication of addresses is also automatically configured.
A default test mode operation is available.
Self diagnostics system
Comprehensive troubleshooting codes allows for a timely identification of possible problems arising.
High lift and flexible piping design
Equivalent pipe length of 150m and vertical lift of 50m is possible with TOSHIBA Super HRM.
Vertical lift between indoor units of 35m is the highest in the industry.
Also the maximum piping length from the 1st branch is 50m.
This allows for greater flexibility within the building design of the system.
Simultaneous operation
By controlling the FS unit, Super HRM enables simultaneous operation of cooling and heating.
This operation meets the various requirements of modern buildings that are highly airtight or have
an increasing heat load due to the use of computers. Super HRM also improves energy efficiency by
recycling of the exhaust heat.
Extended outdoor temperature operating range
By use of sophisticated system control with inverter driven compressors, the operating range
in cooling has been increased from -5
to -10 .

Compact FS unit design
The compact and light weight design of the FS unit (Flow selector unit) allows it to be easily
installed with in a limited space.
Group control by one FS unit
Up to 8 indoor units can be group controlled by the use of only one FS unit, this gives greater flexibility for
various different types and sizes of rooms.
Intelligent control
TOSHIBA Super HRM intelligent controls and modulating valves deliver the required capacity
according to the load variation from 50% to 100%.
The intelligent controls and modulating valves limit or increase the cooling capacity dynamically so
humidity and temperature are kept within the comfort zone.
Conforms to building control law
IAQ (Indoor Air Quality) is also achieved by combining various accessories required by the Building
Control Law.
Wide control applications
Artificial Intelligence Network system.
Central control and monitoring system available.
Weekly schedule operation through weekly timer.
Integration with Building Management System (BMS) is available.

3. Charging requirement with additional refrigerant
After the system has been vacuumed, replace the vacuum pump with a refrigerant cylinder and charge the
system with additional refrigerant.
Calculating the amount of additional refrigerant required

When the system is charged with refrigerant at the factory, the amount of refrigerant needed for the pipes at the
site is not included. Therefore, calculate the additional amount needed and add the required amount to the system.
(Calculation)
Additional refrigerant charge amount is calculated based on the size of liquid pipe at site and its real length.
[Additional refrigerant charge amount at site] =
[Real length of liquid pipe] x
Additional refrigerant charge amount
per liquid pipe 1m (Table 1)
x
1.3
Example : Additional charge amount R (kg) ={(L1 x 0.025kg/m) + (L2 x 0.055kg/m) + (L3 x 0.105kg/m)
+ (L4 x 0.160kg/m) + (L5 x 0.250kg/m)} x 1.3

L2 : Real total length of liquid pipe

Foreword
WIRING DESIGN
1. General
(1) Perform wiring of the power supplies in conformance with the regulations of the local electrical company.
(2) Use a 2 core shielded wire for control wiring on connecting indoor units, and connecting of indoor units to outdoor
units. This is recommended to prevent possible noise issues.
(3) Be sure to connect an earth leakage breaker to the power supply of the indoor units.
(4) Supply a separate power supply to each outdoor unit ensuring use of an earth leakage breaker and isolator.
(5) Never connect 220-240V power to the control wiring terminal block (U1, U2, U3, U4, U5, U6)
(Fault will be caused.)
(6) Locate wiring system for the control and refrigerant piping system in the same line.
(7) Arrange the cables so that the electrical wires do not come in to contact with high-temperature parts of the pipework ;
otherwise insulation will melt and an accident may be caused.
(8) Do not turn on the power supply of the indoor units until vacuuming of the refrigerant pipe has finished.
2. For outdoor unit power supply
Select the power supply cabling and fuse of each outdoor unit from the following specifications:
5 core cable, in conformance with Design 60245 IEC 66
Do not connect them via the terminal block (L1, L2, L3, N).

Determine the wire size for the indoor unit according to the number of connected indoor units downstream.
Observe local regulations in reference to the wire size selection and installation.

Be sure to use the supplied cable. If the length between the indoor and FS unit exceeds 5 m,
connect by using the connection cable kit (RBC-CBK15FE). (Sold separately)

Wire sizeField fuse
NOTE :
The above connecting lengths stated in the table, indicate the length from the isolator to the outdoor unit. When the power
supply of the indoor units are connected in parallel, it is assumed that no more than a 2% voltage drop will occur. If the
connecting length is to exceed the stated lengths, select a suitable wire in accordance with the local wiring standards.
CAUTIONS
(1) Keep the refrigerant piping system and the indoor-indoor/indoor-outdoor control wiring systems together.
(2) When running power supplies and control wires parallel to each other, run them through separate conduits or
maintain a suitable distance between them.
(Current capacity of power supplies: 10A or less for 300m, 50A or less for 500m)

Specification
Shield wire
(1) The crossover wiring and central control wiring uses a 2-core non-polarity communication wire. Use 2-core shielded wire to
prevent possible noise issues. Connect the end of the shielded wires and earth(ground) at both the outdoor and indoor unit.
Where the shielded wire is connected between a central controller and a outdoor unit, only earth(ground) at one end of the
central control line.
(2) Use 2-core non-polarity wire for remote controller. (A, B terminals)
Use 2-core non-polarity wire for wiring of group control. (A, B terminals)
